Spikes in current consumption after using semaphores

[sumit-adep]

can anyone tell me what are these spikes

i am some part of my code:

_SPRINTLN(DEBUG_INFO, "LOW-PWR-SYS-ON"); // debug log to show device will enter standby state

        // turn off peripherals
        pm_device_action_run(uart_dev, PM_DEVICE_ACTION_SUSPEND);
        pm_device_action_run(adc_dev, PM_DEVICE_ACTION_SUSPEND);

        // Block (sleep) the main thread, it will wake up on GPIO interrupt or timer timeout
        k_sem_take(&main_sem, K_FOREVER);

        pm_device_action_run(uart_dev, PM_DEVICE_ACTION_RESUME);
        pm_device_action_run(adc_dev, PM_DEVICE_ACTION_RESUME);

Again original issue which was associated with spikes in current consumption while main thread is sleeping or blocked with use of semaphore is unresolved
+
Plus current consumption of overall pcb is ~10 uA, where nrf52811 SoC is consuming around ~7 uA.

For this refer mode=0.

CONFIG_PM=y
This line does not seem to be doing anything

Agree.

Can you please try to replicate the issue on a DK without any external components connected? Is that possible? If so, can you please upload that sample here?

BR,
